3. Double-click the component to open the Configuration Property Sheet (CPS).
4. First screen in the CPS, that is, wizard (1 of 3) is used to define the service using a user interface for WADL. User can create a WADL manually by defining different aspects of the service or can load an existing WADL and edit the configurations.
   In the first screen, perform the following actions and click Next:
   1. Provide Service Name as 'HelloWorld' with which the event process functionality is exposed as RESTful service.

   2. Go to resource under Resources node. Under Resource Configuration tab, replace the default value of Path 'resourcePath' with 'sayHello' to give a logical meaning to the scenario.
      
      

      Info
      The default method being GET, more methods can be added by right-clicking resource. Request can be configured and more response elements can be added from context menu of the method. Refer <link Method Configuration to the topic> to know more about this.
